Hereinafter, the configuration of the jig for checking the presence or absence of the female thread of the TV module pedestal hinge according to the present invention will be described in detail.
The female thread inspection jig of the TV module pedestal hinge according to the present invention has the same position as four pin holes 11 formed in the TV frame pedestal hinge 10 on the base frame 1 serving as the jig main body and the base frame upper portion. Four pin ball guide rods (2) are installed in the
In addition, at the same position as the four female screws 12 formed in the TV module bracket hinge 10, four screw detection rods 3 are installed lower than the pin ball guide rods 2, and the screw detection rods 3 The support ring (4) and the return spring (5) is coupled together so that the module pedestal hinge is raised and lowered,
When the pin hole 10 formed on the hinge of the TV module descends along the pin hole guide rod 2 and the female screw 12 formed on the hinge of the TV module is guided to the screw detection rod 3, the pin hole 10 is lowered. Stopper 15 is configured in the center of the base frame 1 so that) can no longer be lowered, and both sides of the TV module bracket hinge touch the bottom of the TV module bracket hinge 10 when the lowering is completed. The marking rod 17 provided with the marking portion 16 is installed to be configured.
In the drawings, reference numeral 50 denotes a marking marked on the hinge of the TV module base, and 51 denotes a hinge hole.
Referring to the embodiment of the operation jig for checking the presence of the screw of the TV module bracket hinge configured as described above in detail as follows.
The configuration of the TV module pedestal hinge 10 used in the embodiment,
The hinge hole 51 is formed in the center of the TV module pedestal hinge 10, and four pin holes 11 and four female threads 12 are formed at each corner, and the four pin holes are 3.2 millimeters in diameter and four The female thread 12 has a diameter of 3.17 mm to 3.27 mm.
In the process of forming the female screw 12 in the TV module pedestal hinge 10, a hole of 3.4 millimeters in diameter is first formed, and a punch is formed by pressing with a punch to form a hole push phenomenon, wherein the diameter of the hole is 3.1 millimeters. Let it be as follows.
And, by tapping to form a female screw 12 of 3.17 millimeters to 3.27 millimeters in diameter, the TV module bracket hinge 10 is completed, and thus the presence or absence of the female screw formed on the TV module bracket hinge 10 is examined.
And, the female thread inspection jig of the present invention used for the inspection of the female screw formed on the TV module bracket hinge 10 configured as described above, the diameter of the pin hole guide rod (2) formed on the base frame is 3.2 millimeters, The diameter of the thread sensing rod 3 is 3.17 millimeters.
It looks at the process of inspecting the presence or absence of the female screw formed on the TV module pedestal hinge 10 configured as described above in the jig of the present invention.
First, when the female screw 12 is a genuine product formed with a diameter of 3.17 millimeters to 3.27 millimeters by tapping on the TV module pedestal hinge 10, the TV module pedestal hinge 10 is held by hand and installed on the base frame. The four pin ball guide rods 2 are coupled to the pin hole 11 formed in the TV module pedestal hinge 10 to descend.
In this process, since the diameter of the pin hole 11 formed in the TV module pedestal hinge 10 is 3.2 millimeters, and the diameter of the pin hole guide rod 2 is 3.2 millimeters, the TV module pedestal hinge 10 is guided accurately without shaking and descends. You can do it.
In the above process, the TV module pedestal hinge 10 descends along the four pinhole guide rods 2, and four female screws 12 formed on the TV module pedestal hinge 10 are detected at the same position. Entering the rod (3) will be a little lower.
At this time, the support ring (4) and the return spring (5) coupled to the screw sensing rod (3) are lowered together and the return spring is compressed.
In the above process, since the diameter of the female screw 12 formed on the TV module bracket hinge 10 is 3.17 mm to 3.27 mm, and the diameter of the screw detecting rod 3 is 3.17 mm, the female screw of the TV module bracket hinge is (12) passes through without being caught by the screw sensing rod (3).
Then, the bottom of the TV module bracket hinge hits the stopper 15 and at the same time the marking part 16 formed on the top of the marking rod 17 comes into contact with a portion of the TV module bracket hinge. Marking mark 51 is formed in the case, and in this case, the female thread is inspected and detached from the TV module bracket hinge formed normally, and when the TV module bracket hinge 10 held by hand is released, it is coupled to the screw detection rod 3. Since the supporting ring 4 and the return spring 5 are raised together, the TV module pedestal hinge 10 can be easily removed.
In addition, the female screw 12 is not formed in any of the four holes formed in the TV module bracket hinge 10, and is pressed with a punch to form a chamfered portion, and the hole is pushed to have a hole having a diameter of 3.1 millimeter or less. If there is a defective product, the TV module bracket hinge 10 is held by hand, and the four pin ball guide rods 2 installed on the base frame are coupled to the pin holes 11 formed on the TV module bracket hinge 10 to descend. Let's do it.
In this process, since the diameter of the pin hole 11 formed in the TV module pedestal hinge 10 is 3.2 millimeters and the diameter of the pin hole guide rod 2 is 3.2 millimeters, the TV module pedestal hinge 10 can be accurately guided without shaking. It is.
However, among the four holes in the TV module bracket hinge 10, the female screw 12 is not formed, but it is pressed with a punch to form a chamfered portion, and the hole is pushed to have a hole having a diameter of 3.1 millimeter or less, and a screw sensing rod (3). ) Is 3.17 millimeters in diameter so that the hole formed in the TV module pedestal hinge 10 is caught by the screw sensing rod 3 and can no longer be lowered.
Then, the marking portion 16 formed on the upper portion of the marking rod 17 does not come into contact with the bottom surface of the TV module pedestal hinge 10, so that the marking mark cannot be formed on the TV module pedestal hinge.
Therefore, in this case, since it is identified as a bad TV module bracket hinge without a female screw, it is necessary to separate and process the defect.
